Atari Memory Map
Is there a book that explains the memory locations for Atari computers?

Dan Lguyen

There are several books you may find
useful. When the original Atari 400 and 800 were introduced in 1979,
none of their advanced features were documented and Atari kept the
information secret. Shortly afterward, however, Atari changed its
policy and several volumes were released containing much detailed
information for advanced programmers. These include the Atari
400/800 Hardware Manual, the Atari
400/800 Operating System Manual, the Atari
400/800 Operating System Source Listing,
and De Re Atari. These books
are heavy reading, but together they reveal almost everything there is
to know about the Atari 400 and 800 (most of the information is
applicable to the newer XL models as well). The books can still be
obtained from some local Atari dealers, user groups, and from Atari
itself. If you're
interested mainly in a memory map, the most detailed one is published
in Mapping the Atari from COMPUTE!Books. Although this book was written for the
Atari 400/800, more than 90 percent of the locations are compatible
with the XL computers. Other COMPUTE! Books you might want to investigate are The
Atari BASIC Source Book, which
contains the complete source code for Atari BASIC; Inside Atari
DOS, which contains the complete
source code for the Atari Disk Operating System (version 2.0S),
COMPUTE!'s Third Book of Atari, which has a 1200XL
memory map; and The Atari Collection, which includes a section explaining the
most useful memory locations in Atari computers.
